High guys is there a strain called dro? I saw it in the high times mag once and wonderd, because people here call mids ''dro''.
Dro is short for Hydro. Any weed grown hydroponically is "dro" whether the seeds were $100 apiece or from some crappy brickweed. As you said, it is incorrectly used for midgrade weed a lot.
nope, dro is short for hydro, as in hydroponics, just like buz said. Its not a seed, its a growing technique.
